摘　　要：利用揭阳潮汕机场2012-2014年夏季(6-8月)的雷暴观测资料,分析了揭阳潮汕机场夏季的雷暴特征。结果表明:揭阳潮汕机场夏季雷暴发生较频繁,按日数统计的气候概率达36.6%;一天中雷暴多数出现在12:00-15:00,与气温的日变化基本同步;最多连续天数在1-3 d内;持续时数较短,一般在2.0 h内;雷暴一般形成在南、西南、西和西北部,消失在西、西北和北部,移动方向主要为由南向北。形成夏季雷暴的天气形势主要有副热带高压边缘、热带气旋和热带辐合带3类。Studying the thunderstorm observation data in summer （June-August） from 2012 to 2014 at Jieyang Chaosh.an Airport, the characteristics of summer thunderstorm are statistically ana- lyzed. Results show that the thunderstorm occurred more frequently in summer at Jieyang Chaoshan Airport, and the climate probability reached to 36.6% according to the statistics of the number of days. Generally most thunderstorm events in a certain day occur between 12：00 to 15：00 BT, synchronizing with the diurnal variation of temperature. The number of consecutive days of thunderstorm process is mostly between 1 and 3 days. Duration was short, generally less than 2,0 hours. Thunderstorm tbrmed in the south, southwest, west and northwest of airport, disappeared in the west, northwest and north. The synoptic situations favorable for the summer thunderstorm formation and development can be roughly divided into three classes： subtropical edge, tropical cyclones and ITCZ.
